Midair and pseudo-underwater observation apparatus

Abstract

The observation apparatus provided with the observation wheel comprises a water tank housing fish and being arranged around the substantially lower half of a rotation locus of the observation wheel in which at least an inside face facing the observation wheel of the water tank is formed of a transparent material.

1. A midair and pseudo-underwater observation apparatus provided with supporting legs erected on a foundation and an observation wheel mounted on the supporting legs in a manner of rotating around a rotational axis comprising;
 a water tank arranged around a substantially lower half of a locus of rotation of the observation wheel to house fish, in which at least an interior wall means of the water tank facing the observation wheel is formed of a transparent material, wherein the water tank comprises at least two blocks in plan view, which are arranged independently or connected to each other, and are positioned so that the observation wheel passes between them. 
 
     
     
       2. The midair and pseudo-underwater observation apparatus as claimed in the  claim 1 , in which the water tank is separated into a saltwater fish block and a freshwater fish block. 
     
     
       3. The midair and pseudo-underwater observation apparatus as claimed in the  claim 1 , which an ascending and descending part with respect to the observation wheel is provided at the position lateral to the rotational axis and on the ascending side. 
     
     
       4. The midair and pseudo-underwater observation apparatus as claimed in the  claim 1 , in which a plurality of lighting apparatuses lighting up the inside of the water tank are arranged. 
     
     
       5. The midair and pseudo-underwater observation apparatus as claimed in the  claim 1 , comprising gondolas, provided with acoustic devices. 
     
     
       6. A midair and pseudo-underwater observation apparatus provided with supporting legs erected on a foundation and an observation wheel mounted on the supporting legs in a manner of rotating around a rotational axis comprising;
 a water tank arranged around a substantially lower half of a locus of rotation of the observation wheel to house fish, in which at least an interior wall means of the water tank facing the observation wheel is formed of a transparent material, wherein 
 the water tank comprises at least two blocks in plan view, which are arranged independently or connected to each other, and wherein an exterior wall means of the water tank is formed of an opaque material. 
 
     
     
       7. The midair and pseudo-underwater observation apparatus as claimed in the  claim 6 , in which the exterior wall means of the water tank is covered with natural objects or artificial structures to be hidden from the sight of the outside. 
     
     
       8. The midair and pseudo-underwater observation apparatus as claimed in the  claim 6 , in which at least an inner surface of the exterior wall means of the water tank is formed to have a mirror finished surface. 
     
     
       9. A midair and pseudo-underwater observation apparatus provided with supporting legs erected on a foundation and an observation wheel mounted on the supporting legs in a manner of rotating around a rotational axis comprising;
 a water tank arranged around a substantially lower half of a locus of rotation of the observation wheel to house fish, in which at least an interior wall means of the water tank facing the observation wheel is formed of a transparent material, wherein 
 the water tank comprises at least two blocks in plan view, which are arranged independently or connected to each other, and wherein a getting on and off step arranged to face the position above the water tank of the observation wheel and where an element of a vertical movement is large is structured so that it may move upward at a speed synchronous with the rotational speed of the observation wheel in the direction same as that of the rotation by a predetermined rotational angle, and may move downward at an intended speed.
